Embodiment Construction
[0068]This Specification discloses various catheter-based systems and methods for treating dysfunction in various locations in an animal body. For example, the various aspects of the invention have application in procedures requiring treatment of sphincters and adjoining tissue regions in the body, or hemorrhoids, or incontinence, or obesity, or restoring compliance to or otherwise tightening interior tissue or muscle regions. The systems and methods that embody features of the invention are also adaptable for use with systems and surgical techniques that are not necessarily catheter-based.
[0069]The systems and methods are particularly well suited for treating dysfunctions in the upper gastrointestinal tract, e.g., in the lower esophageal sphincter and adjacent cardia of the stomach. For this reason, the systems and methods will be described in this context. Still, it should be appreciated that the disclosed systems and methods are applicable for use in treating other dysfunctions e...

Description
RELATED APPLICATIONS[0001]This application is a continuation of U.S. application Ser. No. 10 / 872,656, filed Jun. 21, 2004 (now abandoned), which claims the benefit of provisional U.S. application Ser. No. 60 / 480,147, filed Jun. 20, 2003, and which is also a continuation in part of U.S. application Ser. No. 10 / 760,433, filed Jan. 20, 2004, now U.S. Pat. No. 7,179,257, which is a divisional of U.S. application Ser. No. 09 / 955,915, filed Sep. 19, 2001, now U.S. Pat. No. 6,699,243.FIELD OF THE INVENTION[0002]The invention is directed to devices, systems and methods for treating tissue regions of the body.BACKGROUND OF THE INVENTION[0003]Catheter based instruments are widely used to gain access to interior body regions for diagnostic or therapeutic purposes. The size of such instruments are constrained by the need to permit deployment and use within relatively small, confined areas of the body. Still, there is the need for such instruments to carry one or more functional components, e.g....
